1967-P 50C possible DDR

[Shleppodella1]

This reverse looks like doubled die in "STATES" in USOA and MD in "HALF DOLLAR" inscriptions, as well as the eagles left upper wing looks to have doubling in it or is that also MD? OF also has a strike-thru going thru the lower part of the "F". Now if this an actual DDR what P.U.P. would be suggested to look at in order to figure out which one it is because I don't mind doing the work it's just I'm not sure if it's even a DDR to begin with due to it being one of the harder numistic skills to aquire.

In my opinion, pups/markers are specific to a single working die. If you have a single coin, it's difficult to identify the smaller markers. You would have a better chance if you had multiple coins from the same working die. Then you could find pups/ markers that are on all of those coins, if they are within the same die state range.

If there is machine doubling present on one section of the coin, it is a strong possibilty the rest is as well. Some of the letters appear to have just a touch of metal removed from the tops of the letter. To me, those letters look normal size. It also makes it harder when a coin is circulated, since wear on the coin can wash away any important clues.

In my opinion as well, most of the extra thickness double dies are difficult to attribute and even more difficult to convince another collector it is one. The only way I do it is if I have a BU example of the coin with the same date and mintmark and compare the coin in question to the normal example. I think that is very subjective, and for this, I typically steer clear of those, unless super obvious.

Those letters and numbers might represent an older CONECA numbering system.

On variety vista or even https://conecaonline.info the description should tell you where the doubling is documented. Like anyone else, they would have to read each description and make a list of possibilities. Then look at each documented example to see which one would be a match.

Some people find it difficult to understand the difference between worthless doubling and a doubled die. I believe it is pretty simple on MOST. The worthless doubling will be much lower than the primary strike. It may shear some of the coin away. Worthless doubling makes letters/numbers/buildings/animals/ect look thinner or damaged.

Remember, a working die with more than one impression is sunk into a steel working die. The doubling does not move. The working die that has a doubled die has multiple impressions at the same depth, so when the dies squeeze the blank and make a coin, all that is sunk on the working die is raised on the coin. So in theory, those impressions should be at same height on the coin.

Here is a classic and obvious double die obverse Kennedy. Not all will look this way. The spread and strength may not be as bold.

I believe you should have posted this post in the Die Variety Forum not here. I think it would help you if you looked at JCUVE'S comments on Machine Doubling at the beginning of the Topics in the Die Variety Forum section, if you have not already. All I see in your photos of the half dollar looks like MDD (Machine Damage Doubling).

I figured it was MD in HALF DOLLAR but STATES is questionable.

I will move this one to the Die Variety Forum. Shleppodella1 it doesn't benefit you to just post everything in the wrong forum to get someone or multiple people to look. Actually in my oppinion and it's just me, I think less folks who know varieties will respond because your not following the basic rules of the site. No harsh words but I know we have discussed this before.
Thank you for all your posts and the learning experiance. We try to answer what we can.

I put it in general forum because I figured it was safe and I couldn't mess up and get reprimanded. So, what is it for then please? I'm really not trying to piss anyone off.
Thank you for the information I asked for on doubling from you and Gary it helped alot.

Also I will be more careful in putting my posts in the appropriate places with better presentations and photos with arrows.

Morning Happy Friday!!
Any time that you think it maybe a DDR and you add DDO or DDR to the title or RPM to the title I would follow the guidlines and place the post in the Die Variety Forum. This forum covers only RPM's and Double Dies so it helps me to not have to move a post, plus, from what I have seen in the past, at least some folks will view and hopefully will give an answer of what they believe the coin is. Some folks will pass on posting if the coin is in the wrong forum. Just my two cents.
Merry Christmas and have a wounderful coin collecting new year!!!!
